Known as the world’s longest (not largest) cave system, Mammoth Cave offers endless caving adventures.
Explore miles of trails on walking cave tours available to tourists. Or try touring the cave via the 6-hour Wild Cave tour that involves muddy tunnels and cramped spaces.
This limestone cave formed by dripping surface water that continues to seep through sink-holes. The intrigue of the cave is simply described by the National Park Service as, “grand, gloomy and peculiar.”
Experience total and complete darkness and the eerie coolness only caves provide.
Awe at rock formations like Frozen Niagara and feed your underworld imagination with a river trip or a walk on the River Styx Spring Trail.
